Many studies have examined the relations between drug use and sexual behaviors; however, few have utilized episodic data to examine the co-occurrence of both behaviors within the same episode. This study surveyed 403 racially and ethnically diverse gay, bisexual, and other young men who have sex with men (YMSM; ages 18-29) in New York City. Men were surveyed about their sexual behavior and concurrent use of illicit substances and alcohol during their most recent sexual encounter with their main and/or casual partner(s). Logistic regression models were built to analyze predictors of unprotected oral and anal intercourse with main and casual partners. Results suggest that use of inhalant nitrates and alcohol increased the odds of men engaging in unprotected receptive anal intercourse (URAI) and men who identified as middle or high socioeconomic status (SES) were at lower odds of engaging in URAI with their main partner. Use of other illicit substances was not associated with unprotected sexual intercourse. These findings indicate a need to further consider the role of licit substances used by YMSM as a means of further reducing the incidence of HIV infection in this population. In addition, the high rates of unprotected anal intercourse among men reporting a main partner has the potential to be a significant source of HIV risk, and should be further explored among YMSM. © 2014 © Taylor & Francis Group, LLC.

Abstract Objectives: Rates of powder cocaine and crack use have fluctuated among adolescents over recent decades. Little attention has been paid to recent trends, particularly regarding differences between users of powder cocaine and crack-two forms of the substance that are commonly reported together as "cocaine" use, despite having different effects and rates of adverse outcomes. Methods: We examined data from nationally representative samples of high school seniors who participated in the Monitoring the Future study during years 2005-2011 (weighted N = 65 717). Results: Many demographic and socioeconomic variables were similarly correlated with lifetime use of powder cocaine and crack. Income of >$50/week from job increased the odds for use, and income of >$50/week from sources other than a job more than doubled the odds for use. High religiosity, high parent education, identifying as black, and residing with one or two parents reduced odds for use. Hispanic students were at higher odds for use of crack and females were at lower odds for using powder cocaine. Among cocaine users, residing with one or two parents lowered odds for using both forms, and more religious students and Hispanics were at higher odds for crack-only use. Conclusions: Those interested in preventing initiation and adverse consequences of cocaine use should take into account the overlapping, yet different risk profiles of powder cocaine and crack users when developing programming. This is particularly important when considering differences in legal consequences for these pharmacologically similar forms of cocaine.

The current study examined whether parent psychological resources (parenting stress, depression, and social support from friends and family) moderated the effects of early family preventive intervention on parenting among high-risk families. Ninety-two preschool-age children (M age = 3.94 years) at familial risk for conduct problems participated in a randomized controlled trial of a family intervention to prevent conduct problems. The majority of families were African American or Latino and experienced multiple stressors associated with poverty and familial antisocial behavior. Families were randomized to a 22-session group-based intervention or to a no-intervention, assessment-only control condition. Parents reported on their psychological resources (parenting stress, depression and social support from friends and family) at baseline. Parenting (responsive, harsh, stimulation for learning) was assessed through self-report and observational measures four times over 24 months. Previously-reported intervention effects on responsive parenting and stimulation for learning were moderated by depression and social support from friends, respectively, such that benefits were concentrated among those at greatest risk (i.e., depressed, limited support from friends). The intervention effect on harsh parenting was not moderated by any of the parent psychological resources examined, such that parents with high and low resources benefited comparably. Consideration of moderators of preventive intervention effects on parenting provides important information about intervention impact among families experiencing multiple barriers to engagement and effective parenting. Findings suggest that parents with diminished psychological resources are just as likely to benefit. Family-focused, group-based intervention is promising for strengthening parenting among the highest risk families.

Given the disproportionately high rates of obesity-related morbidity among low-income, ethnic minority youth, obesity prevention in this population is critical. Prior efforts to curb childhood obesity have had limited public health impact. The present study evaluates an innovative approach to obesity prevention by promoting foundational parenting and child behavioral regulation. This pre-post intervention study evaluated an enhanced version of ParentCorps with 91 families of pre-Kindergarten students in low-income, urban communities. Assessments included tests of knowledge and parent report. Consistent with findings from two randomized controlled trials of ParentCorps, parent knowledge and use of foundational parenting practices increased and child behavior problems decreased. Child nutrition knowledge and physical activity increased and television watching decreased; for boys, sleep problems decreased. Comparable benefits occurred for children at high risk for obesity based on child dysregulation, child overweight, and parent overweight. Results support a "whole child," family-centered approach to health promotion in early childhood.

Stigma can be harmful to drug users, particularly those in need of treatment. Beliefs and opinions about drug use may influence how individuals view or treat drug users, so research was needed to examine whether specific beliefs and opinions are related to stigma towards users. A sample of 531 adults was assessed to examine how stigmatization relates to specific beliefs and opinions about drug use. Eighty percent of the sample reported lifetime use of an illicit drug. While controlling for demographic characteristics, lifetime drug use and exposure to users, stigmatization towards users more than doubled the odds of reporting that addiction is a choice, and more than tripled the odds for reporting that marijuana and heroin are equally dangerous. Stigmatization, however, lowered the odds of reporting that drugs would be okay to use if legal. Individuals who stigmatize drug users may be under-educated about drug use; however, such individuals appear to be at low risk for use. Beliefs and opinions guided by misinformation may negatively affect users, so public health efforts are needed to educate individuals about drug use and addiction in an objective manner, and treat use as more of a health behavior and less of a moral behavior.

OBJECTIVE:To evaluate the impact of an early childhood, family-centered, school-based intervention on children's kindergarten academic achievement.METHODS:This was a cluster (school) randomized controlled trial with assessments from pre-kindergarten (pre-k) entry through the end of kindergarten. The setting was 10 public elementary schools with 26 pre-k classes in 2 school districts in urban disadvantaged neighborhoods serving a largely black, low-income population. Participants were 1050 black and Latino, low-income children (age 4; 88% of pre-k population) enrolled in 10 schools over 4 years. Universal intervention aimed to promote self-regulation and early learning by strengthening positive behavior support and effective behavior management at home and school, and increasing parent involvement in education. Intervention included after-school group sessions for families of pre-k students (13 2-hour sessions; co-led by pre-k teachers) and professional development for pre-k and kindergarten teachers. The outcome measures were standardized test scores of kindergarten reading, writing, and math achievement by independent evaluators masked to intervention condition (primary outcome); developmental trajectories of teacher-rated academic performance from pre-k through kindergarten (secondary outcome).RESULTS:Relative to children in control schools, children in intervention schools had higher kindergarten achievement test scores (Cohen's d = 0.18, mean difference = 2.64, SE = 0.90, P = .03) and higher teacher-rated academic performance (Cohen's d = 0.25, mean difference = 5.65, SE = 2.34, P = .01).CONCLUSIONS:Early childhood population-level intervention that enhances both home and school environments shows promise to advance academic achievement among minority children from disadvantaged, urban neighborhoods.

Cross-sectional analyses of 904 diverse men and women aged 50 years and older living with HIV in New York City were conducted to examine the unique experiences and needs of aging HIV-positive individuals. Using Minority Stress Theory and Syndemic Theory as guiding paradigms, the authors documented the mental health burdens of the sample with regard to depression, loneliness, and diminished psychological well-being and examined how multiple-minority status and HIV-related stigma explained these burdens. Mediation modeling demonstrated that the effects of minority stressors on mental health burden were mediated by HIV-related stigma. The mediation was significant for the overall sample and for the male subsample. Results suggest that to fully address the mental health burdens experienced by aging HIV-positive individuals, we must continue to address mental health burdens directly, and at the same time, look beyond the psychiatric symptoms to address the structural inequities faced by individuals based on their multiple-minority status.
